Been looking, as last Wednesday’s night ride, admittedly overcast & a bit later than normal, ended as I couldn’t see enough, under tree cover.

Lots of dual XML (T6 and U2) units on ebay for not a lot of cash (£30) would be my first choice over any of the single XML units.
Anyone know what going on with Li-ion batteries being shipped nowadays, sure I read that RM was being funny with them?
Of course, if you want a decent/reliable light with proper (UK) support you need to spend a bit more with the likes of Smudge (MTB batteries) or Neninja (crgmoto).
